What do the
Roman Numerals mean?
The use of Roman numerals in compounds is based on the
indication of the oxidation number (as a Roman Numeral) of each
of the major elements in the compound, e.g. iron(III) chloride.
There is no space between the element name and the oxidation
and Water Reaction
Copper does not react with water. Copper does not react with
water because the oxygen in water is locked into a compound with
one part oxygen and two parts hydrogen.
with Oxygen - Copper Oxide
is a compound from the two elements copper and oxygen. Copper in
moist air slowly acquires a dull green coating (patina) because
its top layer has oxidised with the air. Copper oxide can refer
to Copper(I) oxide (cuprous oxide, Cu2O) which is a red powder
or Copper(II) oxide (cupric oxide, CuO) which is a black
powder. The patina shields the metal from corrosion. Upon strong
heating, it forms a black solid of copper oxide.

and is a blue,
crystalline solid. It is to demonstrate chemical voltaic cell
reactions. A voltaic cell consist of two different half-cells,
connected together to enable the electrons transferred during
the redox reaction to produce energy in the form of electricity.
Hydrated copper nitrate can be prepared by treating copper metal
with an aqueous solution of silver nitrate or concentrated
Copper nitrate can react with both dilute and concentrated
nitric acid. Copper nitrate can be used to generate nitric acid
by heating it until decomposition and passing the fumes directly
into water which is similar to the method used in the Ostwald
Copper sulfate, once referred to as "blue vitriol" and
"bluestone", is a copper salt made by the action of sulfuric
acid on copper oxide. Copper sulfate is often used to grow
crystals in schools and in copper plating experiments to
demonstrate the principle of mineral hydration. Copper(II) sulfate is the compound with the formula CuSO4
Ostwald process is a chemical process for producing nitric acid, which
was developed by the German chemist, Wilhelm Ostwald (1853 –1932).
Some examples of a chemical reaction include most commonly burning, fermentation,
tarnishing and rusting. There are several different types of Chemical reaction
which have been detailed below:
- Substitution reaction
- Combustion reaction
- Combination reaction
- Decomposition reaction
